Application filed May 16, 1907- Serial No. 374074.

ratus; and for this purpose I have shown an Be it known that I, NIVEN HCCQNNELL, of annular weight 24 having flexible chains or Pittsburg, Allegheny county, Pennsylvania, wire ropes 25 extending over pulleys or have invented a new and useful GasPro wheels 26 on the columns, and connected to ducer, of which the following is a full, clear, I the main carrying frame of the charging and exact description, reference being bad to l device.

' i The main frame '11 is annular in form to the accom anying drawings, forming part of receive withnrit a rotary carriage 27 which Is preferably provided with Figure 1 is a vertical section of my improved producer; Fig. 2 is a sectional side plates 28 and 29 which turn on roller bearelevation showing the'parts in a different ings 30, the rollers being placed between osition; and Fig. 3 is a cross-section lookthese circular plates, and upper and lower m downward on the line III-III of Fig. 1. tracks on the frame 11. l T he'u )per plate 28 y invention relates to the class of gas is provided with a worm wheel 31 which is roducers, and is designed to improve the I engaged by a worm 32 on shaft 33 connected feeding of the charge, the poking of the bed, to an electric motor34 mounted on the frame and the operation of gas making. 11. By actuating this motor, the carriage It is further designed to provide for heatmay be turned to bring the pokers hereinafing or superheating of the steam, where such ter described to different angular positions. is used in connection with inducing or forcing To the lower part of this carriage, 18 secured an into the producer.

the hollow water-cooled tube 35 having at its Referring to the drawings, in which I show lower end a hollow head 36 to which the hola preferred form of my invention, 2 reprelow water-cooled pokers are connected by sents the producer body which may be of any pivotal links 38. These pokers are also pivde'sirable size and shape, being shown as provided with a water-sealing trough 3, into which the lower iron shell 4 projects. The grate may be of any desired form, and I have shown a central grate 5 having annular outlets from the chamber 6, to which the air supply pi )e 7 leads. The gas outlet from the top of the producer is shown at 8.

Surrounding the producer, I provide a series of vertical columns 9 and 10 which support and guide the charging apparatus. lhis charging apparatus comprises'a inam frame 11 having brackets 12 provided with Wheels or rollers 14 which engage Tshapcd uides 13 secured to the columns 9. The rame is also provided with shafts carrying rollers 14 engaging guides 15 upon the column 10, these shafts also having pinions 16 engaging stationary racks 17 upon the columns 10.

On the shafts carryin the rollers 14 and inions 16, are provided bevel gear wheels 18 lnterirfeshing with bevel gears 19 on a shaft 20 carried in suitable hearings on the charging frame. This chargin frame carries an electric motor 21 having sl ow motion gearing 22 and 23 connecting it with the shaft 20. By actuating the motor 21, the entire char ing machine may thus be raised and lowered. In order to reduce the work on this motor, I preferably counterweight the charging appawhieh extends within the water-cooled tube The upper portion of tube 39 is provided with an external screw 40 which enga es the internally-thrcaded hub 41 of a gear wheel 42 mounted within a casingAS carried on a tubular extension ,t-iof the turning carriage 27. The gear wheel 42 is engaged by pinion 15 on a vertical shaft 46 having a bevel gear wheel 47 inter-meshing with bevel gear 48 on a shaft 19 actuated by electric motor 50 mounted on the main carrying frame 11 By actuating the motor 50, the feed tube may be forced upwardly or downwardly, thus acting to open or close the pokers 37 At the top of the feed tube 39 is carried a hopper 51 whose mouth may be opened or closed by a bell 52 pivoted to a lever arm 53 on a shaft 54. The shaft 54 extends through the side of a recess in the hop er and is provided with a counterweighte arm 55 at a point external to the hopper.

Between the upper ends of the columns 9 and 10, is mounte a coal hopper 56 having a rotary feed valve 57 with a pinion 58 which is actuated by any suitable means not shown.

In order to seal the top opening of the producer through which the charging mechanism cxtends, I-preferably employ a telescopic water sealing device 59 which is shown in upper and lower oted to the lower end of the feed tube 39- 35, and also through the hollow carriage 27.

injectors 63 which higher level, shown in Fig. 2,

closed position in Fig. l, and in elongated position in Fig. 2. Watensealing device are lifted successively by the tube 35 as the charging mechanism is raised. The water cooling of the tube 35 and hollow pokcrs may be carried out by any suitable flexible or jointed com'iections arranged. to provide for circulation of water therethrough'to prevent crackinp and burn ing out.

With'niy improved producer, .l. prcferably employ a double-walled hollow bosh into which steam is fed from annular pipes 61. The steam is superheated in this bosh by the heat from the bed oil-incl, and thr-n llows through outlet pipe is: to the steam and air femlsteain and air into the bed.

In the use of the apparatus, the policrs are forced downwardlv into the bed of fuel, being of tapering or edge shape in the preferred form, for this purpose. This is accomplished by actuating motor 23. under whose action the entire charging machine forced down. After reaching the desired position "within the bed of fuel whose normal level is indicated by dotted lines. the polzors arc oponod by aetmiting; motor 50, thus forcing down the feed tube, and causing the pokors to gram ually diverge. The lower end of the food tube and tho space between the pokcrs i thus opened, and the charge of coal within the feed tube feeds down within the cavity formed by forcing down and opening tho pokers within the br-d. The charging ma chine is then raised, preferably with the pokers still in open position. and the charge of fresh coal or fuel thus introduced into the center of the bed; while at the-same time, the rising pokers thoroughly loosen the coal of the bed and break up all clinkrr formation. After the machine has reached its tho pokcrs are again closed by reversing the motor 5!). During this closing of the pokors with tho machine in its uppermost positioi'i, tho screwing up of the feed tube will actuate amlopcn the hollow gate 57' ofthc hopper 5o. 'lhis gate is arranged to receive and contain the proper amount of charge which will then fall into the hopper 51 of the feed tube. The pokers now being closbd and the charge roeeived, the rotary portion of toe charging apparatus is preferably turned by actuatinp motor 34 to bring the pokors to a dill'orcnl position. The clnirpin machine is then lowcred at the proper time to again force tho poke-rs into the bed of fuel in the producer,

,and as they are againi'ipencd. the bell 52 will 50 0 on and allow the charge of coal to desrcml trough the feed tube to the centcrol the coal bed. This hell can be opened automatieally at any desired point in the Vfilliczl movement of the charging machine, and as soon as the coal is discharged, the bell is The movable parts of this 1 l l l 1 l l j l l l l l l 4 l 1' i l i l i l l i l l feeding nu chanism,

closed by the action of the counterweight,

and grate 5,-and superheated steam with air will pass in through the bosh injectors.

'lhe advantages of my invention will be obvious to those skilled in the art. Hand pokingnnd looscning of the bed is avoided,

and the bed is thoroughly loosened and broken up by tho power operation of the pokcrs.

The fresh rhargcs of fuel areied in at the llIOSl; desirable portion of the bed without OX- posuro lo the gas; thus prevonting carrying out of coal dust or particles with the gas. The same apparatus performs the charging and poking operations. .hlcasurod amounts of fuel may be fed at desirable intervals, and owing to the peculiar manner of feeding those charges, an clliciont and economical operation is provided with no skilled labor. The simcrhoating of the steam, if this iscmplovcd, is obtained by radiation from the bod of fuel itself.

The producer may be used with or without a water-scalcd bottom, and many other changes may be made in the form and. arrangement of the produccr, tho pokers, the

the operating connec- Lion' etc, without :lcpuiling from m v invention.
